      abstract     = {Previous studies have reported that repeat colonoscopies
                      were often not conducted in the recommended time interval
                      after screening colonoscopy. We prospectively followed
                      participants of screening colonoscopy from Germany for 6
                      years to investigate utilization and determinants of repeat
                      colonoscopies. In a longitudinal study on the effectiveness
                      of screening colonoscopy in the state of Saarland (Germany),
                      participants who had a screening colonoscopy between 2005
                      and 2007 were contacted by mail 6 years after screening and
                      requested to fill in a standardized questionnaire on
                      utilization of repeat colonoscopies. For all colonoscopies
                      reported, colonoscopy and histology reports were requested
                      from the physician(s). Of 6,407 screening participants,
                      2,212 $(35\%)$ have utilized another colonoscopy. Among
                      participants with negative findings at screening (no
                      adenomas), 962 $(22\%)$ had a subsequent colonoscopy within
                      6 years from screening, accounting for $43\%$ of all
                      patients with a repeat colonoscopy. Family history of CRC
                      and detection of hyperplastic polyps were found to be
                      determinants of higher repeat colonoscopy use. As many as
                      $44\%$ of the participants with low-risk adenomas (N = 509)
                      and $39\%$ with high-risk adenomas (N = 290) at screening
                      did not utilize surveillance colonoscopy within 6 years.
                      Utilization was better with higher school education, prior
                      cancer screening participation and if high-risk adenomas
                      were detected, lower among current smokers and lowest among
                      participants ≥70 years. New strategies will be required
                      considering determinants of adherence to avoid unnecessary
                      colonoscopies and to improve utilization of surveillance
                      according to recommended time intervals among patients at
                      higher risk of CRC in the future.},
